tarrant county college / sent account to collections

Started financial aid process 6 months before classes and they still did not process. Received a call that classes had to be paid week before or could not attend. I did not have the money so i sent a letter as requested to be withdrawn. Called to verify the letter was received and someone in administration said it was. A year later I get a call from a bill collector saying I owed them for classes. I've written 3 times to try to resolve and sent my original letter attached as proof and they haven't responded. The bill collectors calling again saying this will be on my credit. Somewhere in this system there is a problem.
